Abstract
An automotive multistage transmission includes four planetary gear sets and six shifting members, and each of the planetary gear sets include three rotary members selectively connected to the six shifting members to transmit torque between input and output shafts, so that the automotive multistage transmission provides ten or more forward shifting stages and one or more rearward shifting stages with few parts and a simple configuration. With this arrangement, the transmission can improve fuel efficiency of a vehicle.
